RAILWAY-SIG NAL.

SPECIFICATION forming part of Letters latent No. 602,676', dated April19, 1898. Application led February 2, 1898. Serial No. 668,872. (Nomodel.)

To @ZZ whom it may concern:

Be it known that I, FILLMORE WILLIAMS, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Railway-Signals; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention,` such as will' enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to devices employed more particularly for theautomatic giving of signals at railway-crossings to indicate theapproach of a train. There is frequently employed in these devices alever or pair of levers to be depressed by the wheels to eect theoperation of the signal, and as the treads of wheels vary in width itsometimes happens with a narrow tread that the lever is pressed outlaterally from the rail instead of down vertically, thereby damaging theapparatus and rendering it inoperative.

My invention consists in means, substantially as hereinafter set forth,for holding said lever or levers yieldingly in their proper positionwith respect to the rail and also in an improved inode of connecting theparts of a duplex lever.

In the accompanying drawings,Figure 1 is a perspective view of myimprovements as employed in a pneumatic signal. Fig. 2 is a side viewshowing the means for connecting the ends of a pair of arms constitutinga dupleX lever, and Fig. 3 is a top view partially broken out toillustrate details lof construction.

In the embodiment of my invention shown the depressible lever is shownto be of two parts l and l, pivoted fiatwise at their outer ends uponpins extending, preferably, into the side ofthe rail. The inner meetingends of these parts or bars are provided with narrow longitudinal slots1b, and the inner side of the part 1 is bent or cut out to form a recessinto which the end of the part la ts, so that the sides of the two partsadjacent the rail shall be in substantially the same plane and'liesnugly against the rail. The slot in the part l:l is enlarged or formedwith a countersink 1c.

2 is a shaft lying at right angles to the rail and journaled to rock inbearings 4 and 4a. Fixed on the end of the shaft 2 nearer the rail is acrank-arm 3, having a T-head 3, that stands across the slot in the armor part l, said head resting in the couutersink or enlarged recess aboutthe slot in the part 1f. On the shaft 2, between the bearing 4 and anadjustable collar 5, is a spring 5, that tends to throw the shaft inwardtoward the rail, and consequently to hold the parts or arms 1 and 10Mnormally in the proper position against or near the rail.

Fixed on the outer end of the shaft 2 is a crank-arm 6, that isconnected with the end of a piston-rod 7 of an aircompressor 9, and onthis piston-rod is shown a spring 8, that tends to hold the crank-arm 3upward, and consequently the connected en-ds of the parts 1 and la.

What I claim, and desire to secure by Letters Patent, is-

1. In a railway-signal, the combination of a depressible lever adaptedto be operated by the wheel of a car composed of two parts 1 and la, oneof said parts having a comparatively narrow slot lb and the other asimilar slot with an enlarged recess or countersink 1, shaft 2,crank-arm 3 on said shaft, and pin 3"- on the crank-arm having a T-headadapted to pass through the aforesaid narrow slots and to standtransversely in the countersink, all constructed and arranged,substantially as shown and described.

2. In a railway-signal, the combination of a depressible lever adaptedto be operated by the wheel of a car composed of two parts 1 and l, oneof said parts having a comparatively narrow slot 1b and the other asimilar slot with an enlarged recess or countersink 1, shaft 2,crank-arm 3 on said shaft, pin 3a on the crank-arm having a T-headadapted to pass through the aforesaid narrow slots and to standtransversely in the countersink, a spring 5 for holding the parts l andlI-` laterally in position, crank-arm 6 on shaft 2, and a spring 7acting against arm 6 to hold the parts 1 and la' in elevated position,all constructed and arranged, substantially as shown and described.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

FILLMORE WILLIAMS. Vitnesses:
